Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
118 words
An adjustable coding reflector for marking objects to be subjected to a photoelectronic target-controlled selection installation, said installation including a scanner, said coding reflector comprising: a. a base plate having reflector positions constructed as windows therein, with at least one row of reflector positions extending parallel with the direction of movement of the objects; b. a selective adjustable slide at each individual reflector position having reflectors on the surfaces facing said scanner for selective adjustment to a reflecting condition by moving said slide in a direction normal to the movement of the objects; and c. at least one groove disposed on the back of said base plate, one of said slides being disposed in each of said grooves.
Claim 2
Dependent Claim
118 words
An adjustable coding reflector for marking objects to be subjected to a photoelectronic target-controlled selection installation, said installation including a scanner, said coding reflector comprising: a. a base plate having reflector positions constructed as windows therein, with at least one row of reflector positions extending parallel with the direction of movement of the objects; b. a selective adjustable slide at each individual reflector position having reflectors on the surfaces facing said scanner for selective adjustment to a reflecting condition by moving said slide in a direction normal to the movement of the objects; and c. at least one groove disposed on the back of said base plate, one of said slides being disposed in each of said grooves.
